Building With Wood: Meeting the Provisions of the 2015 IRC

STD333 – 2015 WFCM Significant Changes and Introduction to High Wind Guides (1 Hour)
Engineering concepts from the 2015 Wood Frame Construction Manual (WFCM), used to develop the 2015 WFCM High Wind Guides, will be covered, along with updates on changes to the 2015 WFCM. The WFCM and High Wind Guides provide designers with time-saving tools using prescriptive solutions (based on structural engineering principles) for wood structures to resist anticipated wind loads. Example problems showing how to apply tabular solutions offered in the High Wind Guide will also be presented.

Learning Objectives:
Be familiar with provisions of the 2015 WFCM and High Wind Guides and relevant references in the 2015 International Residential Code (IRC) and 2015 International Building Code.
Be familiar with changes in the 2015 WFCM and how they impact structural design.
Understand how roof, floor, and wall assemblies and connections interact as part of a wind uplift and lateral force resisting system.
Understand how to appropriately apply tables in both the WFCM and High Wind Guides to determine prescriptive minimums.
MAT 211-Fire Performance of Engineered Wood Products (1 Hour)
Engineered wood products have been used in the construction industry for years. Types of engineered wood products commonly used in residential construction, reasons for their use, practical applications, and resistance of these materials to fire will be presented. Manufacturing standards, adhesives, and fire protection will be discussed. An overview of test standards and approved agencies that verify code compliance of engineered wood products will also be provided.

Learning Objectives:
Become familiar with the ever-growing family engineered wood products (EWP's) and their unique characteristics
Become familiar with standards that form the basis for manufacture, development of design values, and fire resistance for each product
Better understand the use of these products through examples of a wide range of building applications
Be knowledgeable of resources available to obtain more information

DES600 – Tall Wood Structures: Current Trends and Related Code and Standard Changes (2 Hours)
Cross-laminated timber (CLT) has been in use worldwide for over 15 years, but most notably in Europe. Building with CLT has increased in popularity for many reasons including: just-in-time fabrication and job site delivery, speed and efficiency in construction, reduced job site noise and on-site labor force, substitution of high embodied materials with a renewable resource that sequesters carbon, and creating a living or work space that has the aesthetics of exposed wood.

The recent introduction of CLT in the 2015 National Design Specification® for Wood Construction (NDS®) and the 2015 International Building Code has opened up an exciting new chapter in wood construction. The use of CLT alone or in combination with other mass timber elements, such as glued laminated timber (GLT), nail laminated timber (NLT), or structural composite lumber (SCL), is becoming more common in buildings complying with the current code. There is also an effort underway by the International Code Council (ICC) to recognize the use of mass timber elements in taller, combustible construction through the work of the ICC Tall Wood Ad Hoc Committee. This presentation will provide an introduction to CLT including relevant design standards and code references. Examples of various mass timber buildings around the world will be provided and potential future code provisions relating to mass timber will also be discussed.

Learning Objectives:
Be able to define cross-laminated timber
Be aware of code and standard updates relevant to CLT and other mass timber elements
Be aware of notable mass timber structures around the globe
Learn about current tall wood building projects and resources
